The Voice VLAN feature enables voice traffic forwarding on the Voice VLAN, then the switch
can classify and schedule network traffic. It is recommended that there be two VLANs on a
port - one for voice, one for data. Before connecting the IP device to the switch, the IP phone
should configure the voice VLAN ID correctly. It should be configured through its own GUI.
Mode
Indicates the Voice VLAN mode operation. We must disable MSTP feature before we enable Voice
VLAN. It can avoid the conflict of ingress filtering. Possible modes are:
Enabled
: Enable Voice VLAN mode operation.
Disabled
: Disable Voice VLAN mode operation.
VLAN ID
Indicates the Voice VLAN ID. It should be a unique VLAN ID in the system and cannot equal each port
PVID. It is a conflict in configuration if the value equals management VID, MVR VID, PVID etc. The
allowed range is
1
to
4095
.
Aging Time
Indicates the Voice VLAN secure learning aging time. The allowed range is
10
to
10000000
seconds.
It is used when security mode or auto detect mode is enabled. In other cases, it will be based on hardware
aging time. The actual aging time will be situated between the [age_time; 2 * age_time] interval.
Traffic Class
Indicates the Voice VLAN traffic class. All traffic on the Voice VLAN will apply this class.
Port Mode
Indicates the Voice VLAN port mode. Possible port modes are:
Disabled
: Disjoin from Voice VLAN.
Auto
: Enable auto detect mode. It detects whether there is VoIP phone attached to the specific port and
configures the Voice VLAN members automatically.
Forced
: Force join to Voice VLAN.
Port Security
Indicates the Voice VLAN port security mode. When the function is enabled, all non-telephonic MAC
addresses in the Voice VLAN will be blocked for 10 seconds. Possible port modes are:
Enabled
: Enable Voice VLAN security mode operation.
Disabled
: Disable Voice VLAN security mode operation.
Port Discovery Protocol
Indicates the Voice VLAN port discovery protocol. It will only work when auto detect mode is enabled.
We should enable LLDP feature before configuring discovery protocol to "LLDP" or "Both". Changing
the discovery protocol to "OUI" or "LLDP" will restart auto detect process. Possible discovery protocols
are:
OUI
: Detect telephony device by OUI address.
LLDP
: Detect telephony device by LLDP.
Both
: Both OUI and LLDP.
